7.9.4 NMI and LRESET
The Non-Maskable Interrupts (NMI) can be generated by chip-level registers and the LRESET can be generated by
software writing into LPSC registers. LRESET and NMI can also be asserted by device pins or watchdog timers. One
NMI pin and one LRESET pin are shared by all four CorePacs on the device. The CORESEL[2:0] pins can be
configured to select between the four CorePacs available as shown in
